depends on what you want your slang word to mean. Oh BUMP.

Kevin: We don't go to school to learn how to use slang. Slang is the language of the uneducated, or of social outsiders. Most kids aim higher than that. Avoid trying to make slang fit into your communications. Aim for the top rung.

what made you assume that,I was just highlighting the various instances a slang word can be used. one can interpret it within a broad range as you mentioned. slang is not formal and thus can be altered and has no formal relevance or political or social place.:)

I apologize for any misunderstanding. In the context of the sentence "Mr. Roberts sat like a bump on a log through the entire meeting," it is indeed an old term or phrase that means Mr. Roberts sat there silently and without any movement or contribution during the entire meeting. It suggests a lack of engagement or participation. This phrase is not commonly used in modern English and can be considered an idiomatic expression. In general, idioms and slang can vary in meanings and usage based on historical context and cultural factors.
